Sermorelin

Also known as GHRH 1-29, Geref

Sermorelin is the first 29 amino acids of GHRH — the natural signal that tells your pituitary to release GH. It's one of the most widely prescribed GH-stimulating peptides through anti-aging clinics and is often considered the most legitimate entry point into GH peptide therapy.

How it works

Direct GHRH receptor agonist — identical mechanism to endogenous GHRH but shorter half-life. Stimulates pulsatile GH release preserving natural GH axis feedback.

Benefits

  • Increases natural GH and IGF-1 production
  • Improves body composition — less fat, more lean mass
  • Better sleep quality, especially deep/slow wave sleep
  • Increased energy and recovery
  • Bone density improvements
  • Anti-aging effects

Dosing

200–500 mcg · Once daily (before bed preferred)

Bedtime dosing maximizes GH pulse during sleep. Compound with Ipamorelin for synergy.

Ranges reflect commonly cited research protocols, not a prescription. Dose with a licensed provider.
